Thanks Lennysmash

I attempted to add a bit of bulk to the guy's hips with some pouches. Let me know if that helps

I have 30mm bases, but I use those for my actual army. I figured that this guy probably won't see the light of day again, so I just grabbed a spare base. If I ever get serious about this though, I'll definitely use some 30mms.
Thanks for the other tip about cheaper truescaling. I have already attempted some crude form of it down below, so check that out and let me know what you think of that.
I think its safe to call my man finished.
Instead of doing truescaling, I think I'll just attempt to replicate armor variants that
FW hasn't done yet. IE: Make up my own... (or have my design student friend do some for me). The truescaling was fun and all, but the amount of effort going into just one guy, with the half-shoddy outcome just isn't satisfying...
I have also spent a good... 8 hourly sessions (I can count from all the layers..) on this guy's legs. Its my first attempt at layered armor, using Lamenter's techniques. I think for a starter, it came out alright. You can see where some of the lower levels of green stuff has kind of folded/wrinkled because I was impatient and started the next layer after about 3 hours. Mistake. It was just a test, but I should probably go back and sand it down a little. Its not terrible, but after looking at it for a while, it pops out at me.
Also note that sculpting is difficult, and attempting to sculpt something fairly symmetrical on one leg, then attempting to do it on the other is not something that I will ever be good at. I can't even do it drawing with a ruler! D: Woe is me...
And I also tested out a couple other true scale techniques on my pile of random test subjects I acquired from someplace...
Far Left, Calgar: Terminator legs with an extension somewhere in the shin plastic. The feet are slightly angled in from the extension, but its hardly noticeable. The chest was also bulked out forwards and sideways. I used terminator arms, a normal sized helm and a normal sized backpack.
Second from left: Terminator legs, with just some greenstuff around the backs. The chest piece was bulked out forwards, but not left to right, therefor making the model skinnier around the waist. The arms were normal marine arms, with 1mm extensions in the forearms and greenstuff armor resculpted. Normal head, and expanded backpack.
Middle: Extended shins and thighs by 1mm. The legs look longer, but without altering the torso, it looks funny. Also note the wide stance. Not even close to being as tall as the other two marines.
Second from right: Extended shins by 1mm. Not much shorter nor taller than the two marines next to it. You can see that the feet are angled because of the extensions since they are not proportional.
Far Right: Normal snap fit marine.
Let me know what you think about all of that.
