Really, your style seems more focused these days. Cash wise, is it a primary or secondary form of income?

It's technically a primary form of income but I don't have any upkeep to pay until I move out.

In that case, you can probably get away with decently high prices. The biggest trick is to remember to work on it consistently and have a well documented process if you don't have one already. Pitch some tangible pricing models, see how your community thinks of it :)

I mean pretty much I'd say go for what you'd think would be reasonable. Prices around the world are always going up, so such things are to be expected. Even without any upkeep to pay you could always create a savings buffer at least (or waste it all on Video games and art... like I do :D). Ofc, since you mainly deal in TF perhaps having some special deals on those might be smart. Current art mood bonuses or whatever could also be a thing. Though I'm pretty sure you've run all that at some point. So tl;dr I personally understand a price hike, some people may gripe, but I think a lot of people would probably be supportive.

Well, in my experience, everybody undercharges for their services. But since I'm in a bit of a shuffle right now and can't really afford any commissions, perhaps my opinion doesn't mean much.

I know a few artists are doing yearly reviews of their prices. The transition into a new year is a good time to re-evaluate how you've artistically grown and increase prices accordingly. :3

You answered your own question in my opinion. You should structure your prices to fit your needs. If you feel like the current offerings fail to do so, then they need to be replaced. With some of the potential changes you may face next year, it's extra important you do this now rather than later.
