I NEED AN ADVICE!

[elfin niche]

Hi guys,
I was wondering if there is any pro artist or someone with experience in concept art or illustration who could give me some feedback. I've been working on improving my art for a couple of years, but it's tough to gauge if I'm close to a professional level on my own.
Here is my portfolio: https://www.artstation.com/freel127. It includes my best concept art and original illustrations.
For those who prefer not to click on the link, I'll also share some examples of my artwork below.

Thank you!

Wow your art is GREAT and your concepts are really creative and interesting. I like your character design for lem! Your doing good in many aspects. Your colors are harmonious, your composition is well planned, and your poses show the character’s personality! There are a few things though, and take note that i am not a professional, but my portfolio is in my bio if you want to see my work. The few things i think would make your art take that next level is, working on your line weight and confidence, working on depth, strengthening your values, and when it comes to character sheets, just fill them out more, allow for more expressions to be seen, more poses and if possible interactions with other characters. When it comes to character design we want to see character AND design… if that makes sense. The key to a great design is (aside from the many other things) showing personality

Jackie droujko https://youtu.be/b3fk659zNAU?si=eztgLvEyu_CARfMl is an AMAZING resource for seeing how your art will be percieved in the proffesional world, shes great for showing you how to make the art you love easy to hire ❤️

Ethan Becker https://youtu.be/LqYnqUVEJI8?si=e0TFC9ZG-klU02Ov is great at showing design fundementals and shape language (both to help with your line confidence and finding apealing shapes for design) and he explains in digestable bits ❤️

Winged canvas https://youtu.be/tOGDmamxQwE?si=14GEr3uc9hFiJ_Yn is also a great rescourse on almost everything, so is proko. This video will help you see that high contrast = more eye catching. In that cafe peice, i cant really tell how deep the space of the cafe is because you colors on the inside are almost all around the same value, a tip for that is to darken everything behind the main girl!

Again im not a proffesional. Im literally just some 15 year old. But the best advice i can give you is the advice of seasoned artists willing to share their wisdom

I really hope that this is helpful! <33

This https://youtu.be/7m3wGbPMSUY?si=6_F8O-i_aFS5ocmd is a great video that taught me everything i know about line weight, but this https://youtu.be/esHotsI4A_8?si=-BOfK2Au6uDqF9vP may be better suited to your style

I really appreciate your help and don't understimate it, It's very difficult to realize of some problems in your art because you're use to it. Your advices help me to point out things that i could improve, thank you so much! :3
