This anon gets it.
First of all, you have actual, real life studio experience, which is better than just sitting at home modelling stuff, and with what you have described, that would make you intermediate, or, let's just say 'artist', without the junior or senior. I can't tell of course what is the quality of your management skills, but the fact is that you've done it and you very likely had the opportunity to learn from any mistakes you've made. That counts for a lot.
If an 'entry level' artist exist at all, it would be called an intern. Someone young, still in school, just starting out and with only the most basic skills.
At the studio where I work we actually use a guideline doc describing the soft and hard skills you need to have at each level, so I can have a sneak peek at it tomorrow, but what I can tell you is that the major skill that gets you to the top (besides being very good artistically) is communication.
- talking with devs and project management, being aware of what is needed, forseeing problems, offering solutions.
- making sure that all the artists are on the same page and working well together. Assign tasks, provide feedback, set the standard and make sure it is kept.
- guiding junior artists, teaching them, keeping an eye on them and solve problems or recommending them for promotion.
- being able to talk about art on a high level. Not just about skills and techniques, but understanding the intricacies of visual communication and being able to express complex concepts clearly.
- working with outsourcing studios or freelancers, creating style guides and various other documentation.
- etc, etc.
and all these things, in a diplomatic, positive way. Being fair, honest and understanding of different personalities and cultural backgrounds.
