You are making a lot of really good stuff here! Just keep drawing, look at refs when you need to and practice a lot! : )
I thought about making art smut and even tried it for a bit, but I chose to take my skills elsewhere because I didn't enjoy making it. Long story short: even though I stopped making any kind of porn, I still love to see other new artiest that are wanting to do this.
So keep at it man, you're doing an awesome job. ouo b
