Ok, here are some tips.

Make a big thick chunky loop that you like.

Now seperate the loop into individual parts, and add some variation into the parts.

Think about the structure of the tune - do you want it to build up slowly, or just kick in straight away? Do you want it to breakdown then kick back in?

Using the various threads in your loop build up an arrangement, taking things away, putting them back and making sure that there is variation enough to keep your listeners attention.

Aim to make about 6 minutes of music. Then imagine how you would want it to be if you were going to mix it with other records. Add some edits, variation and FX and you are set.

Best of luck.
