Really enjoy the color scheme.

Hey, @Ieva Paleja! Many cheers to you in the beginning of your journey! I totally agree with @Steve Lenze, perspective is one of the key fundamentals you will certainly benefit from by studying and getting familiar with. Another subject I’m sure will help you is value, as it is the base for understanding ways to use colors in painting and illustration. But let’s not get ahead of ourselves! Since you’re just starting out, perhaps a good next step would be to take a course on introduction to digital painting, have you considered that? I know @Jon Neimeister is currently developing his Digital Painting Fundamentals course here at Proko, so perhaps you might like to check it out. Alternatively, I also really like the stuff over at http://www.ctrlpaint.com - some of their more focused courses are paid, but they also have a huge library of free tutorials plus a free small series called Digital Painting 101 (https://www.ctrlpaint.com/getting-started), which I think is very helpful for beginners. Let me know in case you have other questions. Feel free to keep posting your work here at the Proko community and asking for help whenever you need!

Hey Ieva, Good to see you here, and to see you begin your digital illustration journey. I wanted to start with your background. In order to create an interesting composition that makes sense, you need to create a perspective grid. I created a one point perspective over your painting to show you what it looks like, and how it effects the elements in the room. I also added some more detail to your background to make it feel more lived in and give it more depth. Study closely what I did and see if you can incorporate some of these thing in the future. I hope this helps :)
