Hey, I think this tile deserves a 3. This is because: A (good). The black border to your left is not your doing and you tried working around it. B (bad). You failed to give the people on your sides (3 sides!) anything interesting to work with besides a few blobs of color. C (bad). The right hand side of your tile is just black with a smear of red and a few undefined lines that end before the border.
Overall, it shows that you tried, and it's a good try. Keep practicing.

Yeah, thanks for your criticism, that means a lot to me. I first wanted to draw a tree of mana, but that yellow .. well. I´m really sorry because of that black background, but I had noticed the message too late, sorry.

I know the tile is not my best, but after that I tried better [I hope at least XD]. So, thanks again, I´m going to improve my technique ^^
