Are these good prices?

So I take commissions now but I still don't know how to price my art so these are my prices for now but you can tell me if you think there too high or too low.
Also sorry if this isn't the best looking commission sheet I didn't really know what to put on it.

As of now if you want to commission me I'd say you should DM on Twitter justholograms since I check it often. https://twitter.com/JustHolograms
