First Self Portrait with DSLR

[gabvlourenco]

Hello everybody

I bought a Nikon D3300 last month and I'm still trying to figure out all controls and light techniques etc etc

I used a Nikon D3300 with kit lens + one bedroom lamp and a house light - In my gear list I have a 5-in-1 diffuser but I found no use for it here

Please tell me where I can improve, all cc welcome

Thank you!
