i like the van helsing one the best, the only things i see wrong with it, is its slightly over sharpened imo, Plus, im not fond of the green bit around his hat.. the text is good, though maybe a bit of a subtle colour? so that it doesnt distract from the focal.

as for the second, the empty space bugs me a little >.< However, i like the text a little better, just try to keep the text simple and short, imo no more than 5 words.

they are both better than what i was like when i started. Keep up the good work <3
