Delta Kanto Fossils (with images)

Yes, I do realize the kabuto and omanyte lines are fusions. I didn't know that a delta couldn't be a fusion until after I made them, but I still wanted to post my work.

Do you have any recommendations to make the Aerodactyl more delta-like? Should I make the wings smokey like the mega?

What about the mega? Should I take some of the fakemon modifications out? Should I try to make them blend some more?

Also, ignoring what it looks like, would this be a good delta/mega, just based on typing and ability? I haven't been the best at making up new pokemon/deltas/megas because the ones I come up with tend to be either stupidly overpowered (check my mega ninjask [here]) or underpowered (check the mega shedinja on the same page)
