Light... will be enough this set?

[roroarro]

Hi All

I need your advice.
I have the following material:

Nikon D3300 with 18-55 and 55-200 lenses
10’x20’ black and white muslin backdrops and backdrop stand
3 stands with umbrellas (2 whites, 1 black/silver, 1 umbrellas-softbox)

I love portraits and I'd like to practice with familiar and friends... So they could be up to 3 or 4 persons in mixed positions

For lighting I bought:

- 1 Yangnuo YN560 IV speedlight with YN560 TX (The transmitter)
- 1 Godox 300W strobe.

I know that it’s entry level or cheap stuff but it is what my wallet can afford for now. I either know that would be better to have more than two light sources.

I’d really love to save my money, unless I can’t achieve these settings:

- Two steps away from maximum aperture (ideally more then 2)
- 200 ISO (maximum 400 ISO)

So the question… Should I add something? A strobe (like godox)? A speedlight? Two Speadlights?
My budget is 100 USD… maximum 140 USD.

Thank you!!!
