Hello Sihaya, welcome to Pixelopolis.
Critique time, ready?!
The DS is alright. You probably could have used cleaner lines for the edges, though your shading and anti aliasing is okay. Would be nice to put something on the screen, or anti alias the border for the screen so it's easier on the eyes.
The flower is nice, though I have four main critiques of it. 1. The vinework could be smoother in places. Consistent widths of the vines could be an improvement. I like the veins on the leaf, though, very nicely done. 2. The beads of water are also good, but I think that more contrast could help there, with white specular lighting dots, and perhaps deeper and more saturant greens there, which brings me to my third critique. 3. The green seems too saturated, that or the pink is too dim. The lady bug is very cute. 4. I would probably suggest using less shades to color the actual flower. It's a nice composition with good balance and a number of interesting elements to it, such as the chewed up leaf.
The chalice looks to be a mix of cg (brushwork) and pixelled work. I would encourage you to create a chalice of your own and get used to drawing ovals and other geometries in pixel to create ideal curves.
The chocolate loooks more thoroughly to be a cg piece.
Alright, with your characters and the moon, I would suggest some anti aliasing to blend the dark color of the suit with the moon, and try pixeling the subtle dark atmosphere instead. Anti aliasing of the curled hillside and the moon to the background would also be good here. I think you've captured the likenesses very well. Perhaps try something like this at a smaller size to save time and focus on the detail.
Your isometric graveyard: Again, color seems to be an issue. Pixel art, fortunately, is a great way to study color relationships and there are a number of people here that can help out with tips. The gravestones are a bit sharp, but the grass is blurry, and possibly CG? The green of the grass is too monotone. Try making the darker green shade more cyan, and make the lighter green a bit more yellow tinged. This is known as hue shifting, and it can help out with creating atmosphere. Lastly, I think you should look at using a purplish or yellowish tint to the stone, rather than leaving it at a wholly neutral gray. You'll find that adding a blue tint to the stone, for example, that a night atmosphere will be added to the work.
I think your last piece, the trail, is my favorite. While there's quite a bit here that is CG based, there's some effort to articulate the leaves, and the blinking eyes are a nice addition. The gate in the background is good. It needs some AA, though. Again, study anti aliasing to get familiar with softening lines. The bark of the trees is too saturated. It feels as though the foreground is unnaturally lit up. You could compensate by making the sunset and sky colors a little lighter.
Good work with these. I look forward to seeing more, and maybe working on smaller pieces, so you can do some quick studies of different pixeling methods. Good luck!
