The Meaning of Life, the Universe, and Everything.
Four retextures of the classic Steve skin, each themed off of one of the four seasons- and partly inspired by the Serene Seasons modification. If you like these, you can check them out on my Skindex page, or use the texture files below.
That's a nice concept; I'd try and do it myself but I'm lazy and haven't changed my skin in eons.
The spring and winter ones look fantastic. I think the other two could use some more work. The summer skin feels like it's a cross between what summer and autumn should be, and the autumn one is too overdone. I'd also try and make the summer one more unique and maybe give Steve shorts and maybe a shorter sleeve shirt, in opposition to how the Winter one is true to theme with a longer sleeve shirt. The hair going from Brown, to Blonde, back to Brown, and then to Silver seems off; maybe go from Brown to Brown (could lighten or darken the shade), to a less saturated Brown/Blonde-mix (for Autumn), and then to Silver.
I think those changes might help a bit. Right now the summer just doesn't feel summer; it feels between summer and autumn, and because of that, it forces the autumn one to be overdone on color and feel out of place itself (it also needs a bit of variation, or the winter one does, as it's just an Orange recolor with a shorter sleeve compared to winter). Maybe give the winter one gloves and/or a hat?
Could also experiment with changing whether the crown (is this what it is) is there at all. Again, variation would help set them apart in their themes, but giving winter a hat instead might give it the variation it needs as far as the crown thing goes.
Just some personal critique, but I absolutely love the concept itself of seasonal skins. Again, I'd try this myself, but I like not being Steve, haha, and I'm too lazy/not skilled to do it for myself.
