These are the original concept sketches for the core three characters of the series. These characters just sort of came out of my pencil fully formed, even before I knew what I wanted to use them for. There have been some visual changes since - Jamie became lefthanded, and I allowed Max's eyebrows to pop over her hairline - but they're still essentially the same characters that popped out originally.
This is the first donation incentive image I did, a picture of Ellen's thoroughly ridiculous D&D character, Milendra Frostwind, first referenced here. For those of you who are familiar with 3.5, she's an Eberronnian half-elf (Eberron Campaign Setting, page 15) with the half-dragon (Monster Manual I, page 214, using the radiant dragon, from the Draconomicon, page 185), half-celestial (Monster Manual I, page 213), and half-nymph (Dragon Magazine #313, page 95) templates applied, and she's a crossclassed ninja (Complete Adventurer, page 5) psion (Expanded Psionics Handbook, page 19) paladin of freedom (Unearthed Arcana, page 53).
Back when I had about ninety Twitter followers, I promised that I'd do a free art request for my 100th follower (this probably would have had a greater effect if I'd posted it somewhere other than Twitter itself). My 100th Twitter follower turned out to be a spambot, and @Simmifugl had called dibs, so I gave it to him. He requested a shot of the core three characters as characters from my wife's comic.
I held a contest in my forum, to see who could derive the floorplan of Ellen and Jamie's apartment from only the information presented in the comic. Faithful forumite "doctor100" got the closest, and he requested a picture of Ellen and Max dressed as pirates.
This was the first half of the third donation incentive: Ellen and Wallace, dressed as an angel and devil, sitting on Jamie's shoulders, as mentioned in this strip.
This is a shot of the main cast, done in Diesel Sweeties style.
Sojourney became my 200th follower in December so I did a shot of the core cast in a Christmas picture for her. She's a kickass colour-type-person, so I gave her the hi-rez lineart - her version of the picture is here.
It's a little known fact that, on the Dinosaur Comics website, you can alter the URL with the querystring "butiwouldratherbereading" to change the template of the comic. This is a Leftover Soup-themed butiwouldratherbereading template!
Paula Gonzalez (a.k.a. PGA99) became my 300th Twitter follower, and she requested a picture of "sporty-sexy Max".
This was the first half of the second half of the third donation incentive - a noncanon comic featuring Max and some salsa. (The second half of the second half of the third donation incentive was drawn by my wife, and is therefore over here.)
This was the second half of the fourth donation incentive: the aftermath of this storyline, after which Trent says he's going to help Max drown her sorrows in "other activities" (i.e., boning).
Here's the NSFW half of the fifth donation incentive - an alternate universe version of the events of strip #151, if Jamie had been a little more responsive to Max's charms. Because I got $100 total for it, I extended it to two comics (but no further).
This is the second half of the seventh donation incentive - a version of strip #255 without the speech bubbles or the cameo appearance. (And yes, that tattoo is canon.)
