The Big Yin has given you some fantastic advice!

I was fortunate enough to have some advice from him too and since then, my still life has improved, and I'm happy to share some of what I've learned on the way :
1. Doesn't matter what lens you use, a long lens set further back from the subject will 'compress' the perspective and make objects look less distorted, so I don't think using a 70-200 is a problem (as long as your room is long enough!)
2. The 'story' is really important - whether telling a story with the objects, or using the objects to stir an emotion, try to have something going on or it won't be quite as interesting.
3. Don't be scared to scout out charity shops, 'mollies den' type places, your mothers friends, rejects from the local flower shop and your old neighbours for 'stuff'... a bunch of weeds from a neighbour who doesn't garden, plonked in an old jam jar with a snail creeping up it, or a beautiful dying rose in an elegant glass, or a selection of veg tumbling out of a flower pot etc.
4. Try something new - frozen blocks of fruit & veg arranged like Irving Penn, using light boxes, using textures in pp, using repetitive patterns etc
5. remember how colours work together and chose well (i.e. turquoise & orange, yellow & blue etc)
6, try out different lighting techniques - there's a photographer who is local to me thats done a lovely range of images where objects are arranged on a flat surface and sidelit at 90 degrees - beautiful evocative images that are just perfect and unique, I don't have any of her images to share with you but you might want to look at Chichester Camera Club roll of honour

And you don't have to spend loads of money - look at B&Q for 'site lights' and LEDS, very cheap, not quite so good, but if you're inventive, you can get some beautiful effects
7. Don't try to use too many things - 2, 3 or 4 elements at most, otherwise it'll be too much and the viewer will overthink things and wonder more about your message than enjoying the art you've created.
8. Depth of field can be your friend or your enemy - use it carefully and try a few different options to see what works best (some of mine are all in focus at f/8, others are at f1.4 to emphasise just a single element)
9. good luck, share your images, and don't get too hung up if someone says something negative, as for each person who doesn't like your image there will be someone else who loves it with all their heart.
