Included in a sketch is color. (A betta is much prettier with it. ;D ) Both pencil-to-paper and digital sketches are free.
The difference between what I'm selling and what's free:
Sketch of your fish... any number of your fish, really... that isn't as cleanly colored or drawn as the paid-for version. The shading will be none to very little, and there will be a solid, simple, or no background added. Details are at a minimum, as well. If anything, it's a more rough cartoonish look.
If desired, I'm also willing to replace coloring with just shading. A black-and-white picture, really.
These are drawings of your one fish (with $1 per extra fish) that are drawn cleanly (no frayed lines) and colored more detailed (more to your fish's color, no accidental out-of-the-lines coloring). Can be done as detailed as each scale on the body, should the commissioner want it. (I'll need a decent picture though, if at all possible.)
Midgrounds/foreground plants are also included. 1-3 is the limit... more if the plants you chose are generally small. Really it depends on the species of plant to determine how many you can have... I might have to note that in my ad, but if, say, you wanted five Amazon Sword plants, I can do an extra 3 of the rather large plants (unless you wanted them small) for the same cost as one extra fish. The only reason I limit plants is to keep the picture from getting too crowded.
Backgrounds are blurr-detailed... meaning you can have an elaborate castle in the background or a sunken ship in the background, or maybe you just want it to be as simple as a vast space of open water... but it will be blurred. The focus of the picture is supposed to be your fish, anyway. ;)
While commissioned pieces are intended to be the more realistic pieces, I've never quite proven to be a realistic artist. It will be of vibrant color, rather than mature, and there will be some things expressed more than in a real betta. Example: the eyes are likely to look less like a real betta's and more as they're seen in the sketches I've done as posted here.
Color in commissioned pieces can also be converted to mid-contrast black and white. In either case... you betta(s) will have the most detail than anything else.
