Thanks.
No time for drawing today so I'll just throw in a quick comment and then begone.
Well, he probably just meant that the male and female sprites were too similar, and gave you some quick ideas. Tattoos can have any meaning you want them to, as long as you let the player know what they mean through dialog or whatever. You can make the tails shaped a bit differently; thinner for the women? The hair you could make a bit finer or longer, I guess.
I don't think it's a huge problem, though. If I had to guess which was male, and which was female, I'd be able to already. That said, the girl isn't especially feminine looking, either. If you told me she was a guy, I wouldn't object. It's up to you whether or not that's okay. They are lizard people, so you might not care about making the women especially feminine looking, hahah.
Well I didn't say it's supposed to be female yet 2 people took for granted that one has to be already.
I'm mostly focusing on making their colors and anatomy non-terrible and they're supposed to look kinda-cute yet still physically capable.
In the end, they're supposed to be enemy types in a golden axe-ish type of game and and angry barbarian punches them so hard that their bones fly out of their bodies.
Imaginative anatomy is pretty good 
although the first guy's right thigh appears a bit longer than his left. lizardgirl is higher contrast in comparison, more bridging shades would be nice, as Jams suggests.
As to gender distinction, it's certainly hard to make subtle anatomical changes at low res, you really have to make it obvious. Your lizardman is sporting a crop top with veiled thong combination and has implied long hair in addition; you can imagine how that could be misinterpreted objectively.
Yes I will try to look into that leg.
They've always been a mess for me to get right if one points directly forward because lolperspective.
Also that's not quite a crop top, it's a split cape kinda thingy which you can almost not see from the front though.
It's supposed to be tribal clothing and I thought dreadlocks-type-of-hair was exempt from looking girly.
Maybe I'll take the first ones shirt off since it's against the law for males to wear shirts in golden axe anyway (unless you're a dwarf) and turn that fancy halberd into a primitive spear cause it's all a bit too clean-looking right now.
