Angling sprites for platformers has it's benefits.
Changing direction from left to right is a much lesser shift than a pure side view sprite, is much smoother and usually doesn't require turning frames.
Much easier to avoid the repeating silhouette effect that plagues a lot of side view sprites.
The view can accommodate more character.
I'm really liking your sprites, only thing I think you need to be careful with is your rooptile's "run anim".
It can be pretty tricky when dealing with a run anim that is essentially a series of small jumps, I assume he'll still control as if running, just with the appearance of hopping?
I'd suggest making his legs a little out of sync and alternating (left- right, then right- left) so he shifts his weight to his side accordingly (edit- skipping basically

), or maybe go for a raptor like run cycle.
