Hmmm about a picture I think that single picture doesn't fit well maybe give more pictures some circular border,square border,cat picture,big picture  oh and I forgot to add that the windows with lighted version look more better than the not lighted becaause the lighted version got 2 layers and not lightdr version doesn't have it (it look a little bit jaggy) Oh and back to those pictures do you remember this Harry Potter corridors ? (many of pictures) try to experiment with it or give some other furnitures like Oil latarns with orange and yellow light or Wardrobe that cover a part of window.



Looking forward for your next edit ;3

Well about i want to talk about the highlight first because the source of light is on the middle made by moon but the left side is highlighted but right no.About the pot on the right side and his shading is really good oh and i think that window border are on the right side are highlighted on right but the source of light is on the left from them same think is the left side with this window border

Waiting forward for your opinion ;3

Xenon

For me the dragon is really good, and the colors are great. If you think that this is a newbie art then you are not right (Great shading , highlights and shadows). For me it's great and if this is your first pixel art then that means that you are talented. Why am I telling that ? Colors can be always fixed but the figur of this dragon (great control of each pixel)

About the mailbox you should fix the rounding on the top and try to use this blue color for outline than black line it should look better. Details : Bigger news paper on the right + highlight and shadows



Give a lot of attention on highlight and shadows in mailbox on this image

Edit :

Here is my fast edit of this mailbox
