While I do want to do things people in general want, I should mention a few things.
1. High CR creatures, especially dragons, take a long amount of time to do. You know the Silver Dragon? That took me months to get done before I even posted it, and it's barely recognizable compared to the original. Creature of CR 10 or less are usually preferable, though I can try and work on higher ones regardless. I do want to come back to dragons at some point, but right now I want to branch out a bit.
2. I'm not that familiar with Psionics, so I'm extremely hesitant about creating a class that uses them. Same with Incarnum and Binding.
