Ummm Midnight, I hate to be mean but I really don't think you are drawing those bettas. I measured the betta size, the white rectangle that it was in, and where the betta was in the rectangle and they both matched exactly to the photo you copied it from. I can even see just a little bit of green where the leaf was. You could have easily changed the background, added some text that looks like writing on there, and photoshopped to "inhance the color" a little bit. I don't like getting on someones case, but that is cheating. and lying If you can draw that good, why is the picture you had us color on your contest thing not near as "picture-like" as this.
And if I am wrong, I am very, very sorry but please give us some definite proof as to how you could not have copied and pasted this picture.
