Trying to learn NMN, how did I do?

I don't know much about the technique- But you're hell of a lot more braver than me OP, great job

Nice work, I’m going to be going on that adventure soon. The blending is a little rough in some places but overall not bad at all for a first try. I’m somewhat dreading what my results are going to be, hopefully I’ll come close to your result!

I'm not much good at it myself but I think you could go darker in the shadows and try and make sure the edge highlights are consistent with your lighting direction.

Fyi the blue isn't the NMN, the gold is.

Great efforts OP.

I think the skull on the chest reads the most gold since the highlight feels like it's in the right place and the skull has enough midtone covering the whole thing before you hit the shadows. The second peice that looks like you did really well is the wrist on the right arm and the right kneepad.

Throw a couple more mini's at the paintbrush grinder and I don't doubt that the improvements will come even quicker.
