1st one-
I like it. The colors are good, and the white adds a nice effect. 8/10
2nd one-
I dont really like this one. It seems like a lot of filter whoring. Also, the text is pretty awkward. 4/10
3rd one(Your sig)-
I think this is the best one. The fire looks pretty cool, and it seems pretty 3d'ish. Once again, I dont like the text. The shadow on it doesnt look right. What I would suggest is mabey add a gradient to teh text (same as the color of the fire) and than liquify the shadow a bit, and make it look like smoke. 8.5/10
Final comment-
All of these seem to be a lot of filtering, but, besides that, they are all pretty cool :happysad:
