I've been modelling for around 6 months and all I can make is things like
And often I go look at other people's work and I see things like
And every time it happens I just want to quit. I don't think I will ever be able to reach that level... I don't have the creativity, I don't have the skill, I can't even draw for the life of me, so how am I going to come up with such designs?.. How will I ever get a 3d modelling job if I will never get remotely close to these people's work? I've been told to just keep modelling but I don't know how to stay motivated to do so.. I don't know how to improve my creativity..
Did you ever have to deal with this? If so, how did you get over it? How much time did it take you to get to a level, where you can confidently say "Yea, it's good."
The artwork you posted from other people definitely wasn't made by a six month noob. And really the only difference is just how much extra time they put into it. Yours isn't that far away.
Just don't quit. If you feeling down its most likely cause you need sunlight and exercise. Too long looking at screen kills the soul.
Then, as Alex J said, they likely have a lot more time and learning put in. You're doing pretty good for someone who's only been going for 6 months.
6 months ago you knew nothing and now look at the badass art you can make! That is progress and I think you'd serve yourself a lot better in the long run if you take a moment to appreciate yourself. You have to be your own friend and cheerleader if you want to go further.
I mean people will literally just straight up tell you what you can do to get to finished art like that. There can be some frustration in applying concepts because working with computers is like working with a monkey at times, but that is definitely the fast track to studio-quality art.
