The attached illustrations are of the same subject - drawn by the same artist (me) 29 years apart.
First - you should always do the things in life you enjoy. And this means you need to focus on the aspects of those things (participating in sports, playing a musical instrument, drawing, sculpting, writing, etc...) that you enjoy and not let frustrations born of inexperience stymie your moving forward with them.
I witnessed so many young people around me give up on something because they weren't amazing at it or "the best" the first time they tried it.
Ability in anything - any-thing - in life comes from dedication and practice.
In my personal journey as an artist I have gone through many stages of what I'd call "stagnation". I reach a plateau and can't seem to push through it and I step away for a while. I've taken breaks as long as 5 years from illustration. Focusing on photography and music and other endeavors.
I went through a 3 year period while working in medicine where I did ZERO creative things. No art, no photography, nothing. I was too busy working. From this period I started taking photos in the operating room.
One path will often lead to another. If it is organic and feels right - don't resist it.
My illustration ability took a light-year jump forward when I attended film school. I learned to look at light as a character - part of the story - with it's own story to tell. And this has helped me approach how I design and plan for illustrations.
The point of all of this is simply - don't give up on something because you don't get the results you wanted or had expected immediately. You need to practice as often as you can by looking at what you did that worked and what didn't work in your illustrations.
This goes for sports, writing, music... etc... You look at anyone who has accomplished a mastery of a skill and you'll see countless hours of hard work to reach where they are.
Lastly, NEVER - EVER - NEVER - EVER let someone else take something you love away from you by making you feel ashamed or embarrassed by what you create. We are individuals and as such, we all have our innate strengths and challenges. I've known many amazing artists who struggled for years and years to finally reach a place where they felt their art actually conveyed what they had wanted to share.
There are people who for whatever reason - say hurtful things about other people's expressive creations. And this is truly shameful.
We should - as artists - respect each others journeys and be patient and nurturing to one another.
I could never feel good about my own journey by discouraging another artist in theirs.
Just some things to think about.
Be kind to yourself and be kind to each other.
