Hi. I think your sprites are great! My favourite from your palettes is the one I edit below.
Looking from afar there's really not much to offer in terms of critique. Your designs are solid and your pixel skill smooth. The edit above is if you're really really interested in pixel placement and stuff like that. Most of what I did to your sprite is remove 45 degree angle banding. You're adding these intermediate shades between darkness and light to make gradiations, which is a solid idea as transferred from normal drawing in mediums where you're not confined to pixel grids. However there are some things in pixel art which are counter-intuitive about how 40 degree lines work. Take my edit with a grain of salt on this front, because it's related to how much you may or may not feel banding hurts a piece of pixel art. If you're okay with it, disregard that aspect of the edit. It's one of these 'once seen, can never be unseen' things for me, so removing of banding is a top priority for pixel art made to be displayed in crisp high resolution screens where the grid is very visible, but you might feel different.
Besides the de-banding, I messed around with the volume and the shapes of your character to suit a slightly more realistic sense of physique, again this is completely optional in my opinion, you don't have to make your anatomy any more realistic for what you're drawing (cyber space armor lady), but perhaps it'll be useful as a different vantage. I do think the way I re-shaded the upper legs is an improvement, because your original was lit in a strange fashion, as if the character's legs became darker the closer they moved towards the knee. I'm not sure if you're trying to convey some different sort of pants, perhaps more poofy, that what I went for.
There's also some spice added to the palette.
The biggest thing to take from my edit is that you light things too uniformly. The dark areas and the highlights are roughly equal in size, but highlights, in order to pop, need to be significantly smaller than the main color they're shading. But at the same time you need to avoid single pixels of detail, they just end up as noise for anyone who is not going to stare at your character standing still for 30 minutes at 2x zoom or more. I disambiguated the distinction between helmet and shoulder, for example. Made the eye structrure clearer. Lots of small stuff like that. If you switch between edit and original in your pixel app you'll find a lot of minute changes that may or may not be of some use to you. The principles with which I am editing, as always, can be found in the Ramblethread on the general discussion board.
And if I may quickly comment very quickly on the secondary topic raised: Pixelation does not currently consider 'I like it' or 'you're on the right track' to be valid pieces of critique. Encouragement is wonderful, but we try to keep the boards critique-packed. Every post, if possible, should have both positive and negative aspects highlighted. Any sort of one-liner, unless it's a completely 100% on point crit that nobody has noticed, usually is deleted. If you're looking for emotional support, a critique board is not where you should go. There are many places on the internet where creativity is celebrated in itself, but Pixelation is useful because it is
not such a place. If you are not getting a lot of critique for your work that means that the people that browse didn't find anything glaringly wrong with your work. That is great! You should carry on with your project, in this case. Of course people whose artwork has glaring issues are going to recieve more attention, because that's the function of a critique board. What we celebrate here is artistic growth. If you're evidently all grown up already, why not start helping other people more instead of asking for attention for your own stuff?
