Yeah I have a black one floating in my left eye that I got last year. Pretty annoying but i try not to focus on it too much and try to wear sunglasses more often when I'm outside.

Depends on your use case. Why are the apps you've used inadequate? What are you trying to do?

Hey Rachel! This is a great question. Have you talked to the senior designer about this situation? What was their response? Did you raise this to your manager? Your concern is valid and if I were in your shoes I'd bring it up. If the the issue is that he thinks the quality of work is not to par - ask the designer what would make it better.

How big is your team, do you have other designers you could learn from? How's the local design community where you're at? I'd also get connected with other folks and find opportunities for mentorship (not just on the design side but on ways to handle some of the collaboration stuff at work)

I recently wrote an article about self-assessing skills as a designer - take a look and let me know if there's anything that resonates with you there
