I was very enthusiastic about this project. I felt like there was an opportunity to have a lot of fun with it, which is exactly what I did. It's also why I chose to do an extra poster just for fun.
I chose to tackle all three themes for my posters. The "Dirty Moby" show poster uses a lot of composition from several photos. I changed the sky to include the (somewhat symbolic) stars along with the "stars" of the show. The performer on the stage is indeed Moby, but he was cut out from a different picture and placed there. Obviously, the same is said for the huge TV screens on the edges of the stage. I really wanted most of the attention to fall towards the center of the piece. Texts is used sparsely, though in hindsight I probably should have included some form of contact information. I used the selection and edge refinement tools a lot more in this poster than any other piece. I made some lighting adjustments to Moby's on-stage persona as well so that he fit in naturally.
The Tea Party poster is my propaganda piece. It's relatively simple, though I spent a long time making the American flag-themed skull and crossbones fit nicely and realistically on the tea cup. The text is very large (minus the "drink democratic" line) with the idea that this poster would be used at some kind of rally or protest. However, I feel that it would be just as effective if hung up somewhere as a static advertisement as well. I used red for the TEA PARTY text since it's a color often associated with something bad, poisoness, evil, republican, etc.
Finally, I chose to make fun of Justin Bieber with a movie poster. I placed Bieber in a hair salon, then prettied him up a bit with some makeup (paint brush + low opacity.) I chose a somewhat girly round font to compliment his... girliness. On the font I added a white stroke around the edges and gave it a 3D emboss effect. Since he (err she) wants to be a boy, I chose a light blue color for the font. I also added a quote from a respected critic, and found a "movie poster" font for the text at the bottom. Apparently this style of text is industry standard at this point.
I want my posters to affect my audience in a humorous way. However, the Tea Party poster is more of a serious metaphor. Some Tea Partier confronted me about it, saying I was a "Typical libber who wants to kill anyone with a different opinion." I don't think he knows what "metaphor" even means.
