Maybe tey doing a little bit of shading on yoir comics? Although I already think they are good, so feel free to not do that if you want to save some time.

I'm no artist so please take what I say with a grain of salt. but sometimes it might be worth looking back and maybe redoing an older piece for a bit of prospective like one of your old single page pieces or simple sequences. having a bit of a comparison like that can sometimes give a bit of light.

But I think all your work is great.
