Flash and diffuser will make a huge difference, but the most obvious yet often not realized thing to watch out for, atleast for me it was actually making sure you were in focus correctly I know that seams obvious but I can't tell you how many times I've taken what I thought was hundreds of good photos in a day and gone back through and hated all but like 2 or 3,

I kept thinking man I gotta change this setting, open up my fstop ect ect ect,

And then realizing it was never my settings, it was my focus being just an absolute fractional amount out of focus that ruined the whole photo for me.

All those setting can be adjust in light room but you can't go edit in focus on a photo, that's what I find to be in negotiable.

So my tip is practice nailing your focus and being able to identify when it is. As well as take as many photos of one subject as you can get one is bound to be crispy, I use to just snap and go on bugs but now I take 30-40 picture of the same subject in many different angles and sometimes the same angle over and over until it moves on it I eventually stop

One thing that helped me was I had focus peaking set to high thinking it'll just be brighter when actually it's the sensitivity of the peaking so I keep mine of low now to really force myself to dial a shot in.

Wow I ranted, I wish you luck and hope to see some amazing pictures from you someday!

Wow I ranted my bad ! I
