Hey Tits (or Marie-- i feel a bit odd using your moniker)
Some nice stuff here. Right now your 2d is far and away your best work; you show a solid sense of anatomy and each piece as a whole works well. On the 3d end, you have a lot of the general proportions right but there's a lot of mushy bits and muscular detail that's off.
For example, both you male and female pelvises are off: the woman's buttocks bulge oddly and the man's legs and pelvic region have a lot of weird shapes going on. His legs are too stout, the feet are too narrow and lack much of a foot's normal contours (for example the achilles tendon should taper more), and the nether region has some weird connections.
Overall, it looks like you only had side reference for the male and were just working from memory on the female. Posting your reference pics, even when you're creatively deviating from the source, helps illuminate where your mistakes are and helps us to crit your work, so post'em if you've got them.
btw, sorry I can't do a paintover right now-- I'm travelling at the moment and won't be back at my workstation for a few more days, but once I am I'll see what i can do. Until then I've got some anatomy orthos that might be of help.
Take a look, though keep in mind these are nudes and thus highly NSFW
anyway, keep it up-- not a bad start for first time modeling a man especially considering it's a speed sculpt. As a general note what i'd recommend doing is painting the trouble areas like the feet from different perspectives and then have another go at modelling them. You'd be surprised at how much 2d studies force you to properly learn 3d information.
oh, and welcome to the club-- glad you decided to start posting. I saw that you've had a few false starts in the other threads, but don't worry about that. The WAYWO thread tends to only draw replies on higher profile stuff, and if you want to get crits in the P&P forum it helps to have a more sustained project; a lot of people don't even bother looking at threads with less than a page of posts, so the next time you start a big project thread first make sure you have something worth showing and then post regularly and post often to make sure you get more traffic. Hope this helps, and keep it up
