I like how The Crater's Boiler Room graphics are getting a modernized upgrade for another purposes, though having two lava surfaces on the layer 2 bg strikes me as an odd choice along with the lighting source on the front rock wall (well, more specifically, how the top-left of the rock is shaded as darkest even though I get that its supposed to have light coming upwards from lava.).
EDIT: Retracted part of the statement. Turns out that the choice is perfect on the rocks. What I will have a suggestion is having rocky spires stick out on the lava to make the liquid base be less "empty".
Modern Redrawn Mario Bros. 1.4 (last update - October 2nd-22nd, 2022, was making more refinements to Small Mario Bros. forms I can't fully remember off the top of my head)
On Pixel Art Requests: I generally do not accept work unless I either have the time, if I see your project worth my time to contribute towards, and that is usually me doing the approaching to you on that.
-I also do not accept speculative work as I do have various art I made on-hand with me.
-I am more receptive to equivalent exchange of resources in which case, you can DM me wherever I have an active presence on for the details.
-Other times I'm availible for your project is C3 request threads I may run.
