Though I achieved recently FMJD grandmaster norm in composition (10x10), I composed only few problems in English Draughts. Somehow board geometry and games rules in English draughts are restrictive and don't give alot of chances to compose position which meets all criterias (see RI rules on FMJD site and latest changes by CPI).
Shortly, the major requirements to composition are:
1) Economic material: no extra white or red pieces allow.
2) Economic solution: no duals or alternative play allow.
3) Clear economic final position - no extra pieces in final position.
Here are two my problems which I composed back to 2004. There were few more problems, but I didn't record them.
#1. White to move and win.
