These are sets i've done over the years oldest to newest.
First set i made, just fiddling around with the mapping (original work)



again fiddling with the mapping and the images (un-original using online images and portal textures found ingame)

also

i changed to



This was all made using GIMP

is there any noticeable improvement?

I don't want to be a fag here but there is not too much improvement it just looks like your spent more time on the last one, but the last one IS better! So good!
But you need better heads for all the rest, the sets are pretty ok but the heads make the set feel like shit, sorry gots to be harsh so you can get gud

These seem more like images + a head than a set.
that's what I think, try making them more focused.

Your getting there slowly but surely, well done keep it up and are they 512?

They are 128. The head is texture 512 rez, but the item is 256 so its scaled down

What can I buy with 270 tc?

The last set was the best, others are more simple. When making a set, start at the head and try to do something detailed, the rest of the set must accompany the performace of the head

I like the last one the most, I'll give 10/10 compared to mine, they look horrible. I hate the first one because.. I like dark coloured things.

last one looks good. White parts on hands doesn't really fit in though.

yea maybe make the hands where the white is black
