Gaz, they're good effort's considering the dabbler's are one of the most difficult flies to tie while still keeping everything in proportion and where it is supposed be.
A question, what thread are you using to tie your flies ?
A suggestion and not a criticism from someone who is hardly an expert. When I came back to tying and saw all of the artistic efforts from some of the top guys on here I tended to try and get a bit artistic myself when I should have been concentrating on basic techniques. These techniques can only be learned from tying " standard's " and following step by steps from guys like Davy Macphail, Scotfly, Stan Headly etc., etc., If nothing else you have a finished article with which to compare your final effort.
It's great to tie something that's your own creation but the satisfaction in being able to tie a perfect Black Pennel or Peter Ross for example will only lead to perfect presentation and proportion when one of these days you produce the " Busbiegaz Killer "
Apart from anything else it'll save you a fortune on tying materials.
