Nice work on both. on the AIDS poster, it looks great, but as far as meaning is concerned it is severely lacking. The message right now is just, "SIDA" with no context. And the symbolism doesn't really make sense. I understand you were trying to avoid established icons, but if you are going to introduce new icons, there needs to be some sense to them. The knife in the tomato or rubber ball or whatever looks sweet in the piece, but doesn't make any sense. And the faded text and cards that say "SIDA" are neat, but there is not a whole lot of context to the piece. You could maybe add some grungy or clipping mask text that is smaller and is some definition of AIDS or monologue from a victim. That could really add a lot of meaning. Once again, it looks awesome, but is really lacking at this point IMO, sorry.

And the book cover is freaking awesome. Great work on that. The only part that seems out of place is the font that says "ilustraciones por emiliano gordillo" it's really sharp and seems harsh compared to the rest of the elements on the piece.

Overall, awesome visual work on both, 1 could use some more context.
