Hello, you guys seemed nice so I am here to learn. This is my very first pixel art [also my very first post here] and I do hope this is the correct place to post for I would like some tips on how to improve. I use paint.NET and I have read through the whole tutorial that is here. I would like to hear some suggestions on what I could do to be better for my next picture and it would be nice if anyone has suggestions for my next picture. I think I did ok for a first try but of course, that's a first try. Nothing looks good without practice.

Here is my attempt at a non-isometric [I'm pretty sure that's what it's called] pixel art of the speaker on my desk. I only did the black part of the speaker and I didn't include the "Logitech" symbol on it because I didn't want to deal with that yet as a first try. Please be nice to my lame speaker but still be tough with the critique.

I do not recommend a beginner try to copy real objects in the style of pixel art. Try to use real objects as a source of inspiration.
Make an isometric box like your speaker. Do not try to make an exact copy of it is not interesting, and looks sloppy.

Не советою новичку пытаться копировать реальные предметы в стиле пиксель арт. Попробуй использовать реальные предметы как источник вдохновения.   Сделай изометрический ящик похожий на твой динамик. Не пытайся делать точную копию это не интересно, и выглядит коряво.
