I have yet to succeed, what should I think about changing?

So for about the past 2 weeks, I've been waking up multiple times at night to get in some WILD attempts. I've been going to sleep at 2 AM (been keeping it pretty consistent), and I set my alarm for 6 AM. I stay up for between 5-15 minutes, reset my alarm for 7:30 AM, and attempt to WILD. repeat at 7:30 AM, set my alarm for 9, wake up at 9, and then sometimes set my alarm for about 10:30, or just get up when I get up.
Now for when I actually attempt to WILD, I'll lay down in bed (on my stomach or side, like I'm going to sleep normally), get comfortable, and then start counting breaths. I usually get somewhere between 30 or 200 counts before I just fall asleep. Sometimes I get Hypnogogic imagery, where I'll try to pay attention to it, or I get nothing, where I might try to visualize something on my own. I think this is the point where I'm getting stuck.
When I first started this, I managed to get one lucky DILD that lasted a few seconds, but I couldn't stabilize my dream vision (I tried rubbing my hands and it didn't work), so I woke up. No lucids since then though. I've also been doing frequent reality checks (especially while I'm up before an attempt).
I'm thinking maybe I need to change the times at which I'm waking up and see if that helps. I think I also might need to figure out what to do after counting breaths. I'm not really sure. Any experts out there who can shed some light on what I might be doing wrong?

Count breaths until you feel you are getting close to sleep. Normally this will happen when you find yourself losing count a few times, or having stray dream-like thoughts entering your counting. Once this starts to happen, stop worrying about your breaths and your body, and counting. Think of a vivid recent memory. Something tactile, involving movement, touch, speed, ect. For example, you could imagine running down your street, and jumping over a fence. Try to get some extreme movement in there, such as falling, jumping, or rolling. Something where you feel it in your gut, like a rollercoaster. Use a memory so there is no work involved. It is not a conscious and forceful visualization. It is something that is already in your mind.

Run this memory / visualization over and over in your (now foggy) mind until your dream body starts to feel convincing and real. It will start as a daydream, but should take over if you keep at it. Keep your dream body moving and interacting with your surroundings.

Don't worry if you ping-pong in and out of reality a bit. Your attention might be divided between your body in bed and your dream body. You might have to start counting again if you find yourself getting too lost in your thoughts. You might get some on-and-off vibrations and sleep paralysis type symptoms. Don't worry. You haven't missed your chance. You will bounce around for a bit. Just keep doing what you are doing, and eventually the dream will take over when you hit a REM state.

Thank you for the tips!
I'm smack in the middle of final projects and tests (even during the weekend), so I'm not sure when I'll get to try again.
I'll come back if I encounter any more problems though.
