It's called critique. Take it or ignore it.
Anyway, the building is just a recolor of the one from Mt. Ember in R/S. Nothing too impressive. The recolors are alright, just next time try making the difference between the colors a little less dramatic. Also, try some better colors. The fusions are prettygood, though Eevee's tail blends in too well with its wing. For the revamps, try alter the shading to fit with FR/LG's standards. Also, try different colors for the outline (Just don't make it a single color). For the devamps, they usually use about 2 or 3 colors. Next time, don't just take away the shading, add dull colors, and make the outline black. For the shadeless, nothing to complain about.
