I have, but I didn't use it. One evidence is the outline- its crooked, making it a possible suspect for the hard to use mouse. I did however, use Adobe photoshop's fill tool.
Hey Secretmapper... Do you have an art thread here? Might as well be honest with you and tell ya I sincerely doubt you did that drawing that fast :/ So I wanna see some of your other work to... Well, get convinced.
Still, though, since there's apparently a few people going "made this in ten minutes", I shall join in.
Made this in exactly 12 minutes. Would have been 10, but forgot to look at the time while colouring.
Used my tablet because I don't have a mouse at all, and drawing with touchpad is so darn tedious and slow.
Really, any art that support your acclaimed skill level would be good.
'Cause... It looks like you picked an anime drawing off of Google images or something and edited it clumsily. It it's actually a swiftly done mouse drawing, it is ridiculously well done, but it doesn't particularly look like it. Hence... Prove your skills a bit more, kthx.
