How can I improve this painting?

You perspective is off. Depending on what medium you are using (oils or acrylics), it may be difficult to fix.

The first thing is deciding whether you see the top or bottom of the viola. If your view is from below, then you will not see the side section on top. If your view is from above, then you will not see the side on the bottom. If the view is from the center, you would not see either. I suggest nipping out that little section of the top side and fluffing up the cloth (towel?) underneath.

It looks like you mixed black or white with your burgundy to create shading and highlights. It is too late now, but next time try to use green to shade and yellow to highlight. This will make the highlights a little brighter. (These are good answers for how to improve if you are also asked for feedback.)

Just for future reference, you needed to make the neck of the violin straighter. However, don't trash the whole painting for a little mistake. I would add a bow next to or around the violin. If you don't know, the bow is the stick-like thing used to play the violin. It looks like this:

Oh, and a violin has three strings. A bass has four. And don't listen to the idiots who are telling you to stop painting. Continue to paint. You're obviously great at it!

Too many highlights on the bottle, too distracting, they tend to pull the viewer in that direction. Tone down, blend or eliminate those not essential to the painting itself. Use wider blended confident strokes, your short thin highlight strokes convey a sense of unsureness with the effect and makes that side of the painting a little too busy compared to the other objects.

Okay its a nice painting. but if you want expert advice then ill give it since ive taken arts as well.

firstly the guitars handle. you havent made it straight. it seems like its melting down. i understand you have given the slanting look, but it just doesnt seem right.

also the bottle.check your proportions. they arent right. both the guitar and the bottle need to be symmetrical.

anyway i cant say much. what ive said may not be true, cause of the angle you have taken the picture, anyway good job! hope i didnt sound harsh. just trying to help!

Its a very pretty painting. But maybe you should chage the color of the brown vase thing, due to the guitar being brown as well .Itll make it pop a little mor. Or make the guuitar tan. Nah, stick with changing the vase color. Unless you like itt eh way it is though. Your the artist, its all up yo you =)

Hope you do good!

I think it is good already but you might want to sharpen the edges a bit by outlining in a darker shade.

That's very nice, I would say the only thing I find lacking on it is a signature. Make that bad boy your own.

It looks great but I would put a rose or some kind of flower hanging over the instrument.

You are very talented! Nothing, it looks perfect.

Hope to see your paintings in a store one day,
