Logo size mobile view

Hello, firstly I’d like to thank the developers of the Hueman theme. I think it’s the best I’ve tried – very clean looking and nicely customizable.

My question is about the way my logo looks on a mobile screen.

My logo is presently in the left of the header area via the customizer.

It is very small and I wondered if someone might help me with how to resize it and possibly reposition it too so that it appears in the centre as oppose to the left.

Thanks in advance for any help.
