That's a big improvement on the old one. If you're going to continue in the R/S/E style, let me make a few more in-depth suggestions to make it go from good to great:
-I like the shadow you've done between the yellow and the light blue. Considering that we're not constricted to the GBA's limitations here, why not expand that to other sections of the screen (don't go overboard, 'cause that'll just make it look busy). But do go for a more complex shadow around each of the pokemon boxes (and the section where the edge meets the background on the first pokemon).
-Pokemon selection boxes: Use a color that more closely matches the blue in the background on the individual boxes. Also, instead of that drab, two-tone "gradient", why don't you use a more clean and modern style (of gradient)? When the box is unselected, I would suggest putting the darkest shade of blue in the center, and then working brighter as you go out on both sides (don't be cheasy! Go manual for this procedure!). When it is selected, I would suggest putting the lightest shade of blue in the center, then getting darker toward the edges.
-There's a small bead of blue on the bottom of the box that says "Choose a pokemon." It may not seem like it matters to you immediately, but trust me, it does.
