First off, change the title to include "Deck/ADV" or "Deck/TRAD",
to let us know if you want it to be traditional or advanced format.
Judging by your deck, you'd want traditional.
Second, lower the card amount.
52 cards is too much for what you're going for.
Some of them aren't even helping the deck flow (like Sonic Chick),
and you have way too many singles.
Try to shoot for around 40-45 cards.
Your deck seems to be all over the place,
with both Blue Eyes and Red Eyes archetypes being there.
I would suggest against cards like "Malefic -",
and your field spell.
The field spell is doing you no good, really.
Take out cards like "Luster Dragon #2",
and "Lord of D", because they're not that great.
Also, I would take out Supay and it's Synchro,
as they're way too situational, and not really helpful for the whole deck.
Also, among other things, why Trap Hole main decked?
I'd suggest Bottomless, unless you're up against Six Sams.
This is just some quick look over, not too in-depth advice.
