Flash is not the best choice here (imho)
All so a wider frame would help to include the whole color tube (the yellow one) in to the frame(since this is a set up you should be careful with this "small" details.
Focus is good but a bigger f number would help so you won't have a shallow depth of field(when you take close up shots you should use the highest f number on your camera to achieve the maximum "in focus area" on your subject).
Over all a good attempt!!!!

thank u, still learning it all, any advise is welcomed

I agree... nice idea but lighting could be better. Depth of field too.

great idea

Nice, but need to get all of the bottles in (yellow cut off a little). Might bump up the contrast a little. If you can't get the yellow in, you might crop an equal amount of the other side out.
