My 2 pennies worth: I'd take away the modal window from the start, signing in with fb or twitter accounts is a first class task and should be treated as such, graphically, editorially whatever. As it stands with the darkened "I like too" etc. buttons it feels like I missed a step, or some piece of the story. I'd also suggest you stick to one shade of blue if possible, make your border radius the same or in harmony and make the generic icon look less like a squashed fb icon, i.e. make it unique or charming, identifiable to your project. Animating the movement of the modal box was probably wasted on most :) Can't say much about anything else as I don't have twitter and I don't use FB to log in to other apps.
