am i considered attractive to women (based on these proportions alone)?

No, you won't be considered attractive based on these alone

throwing a broad definition at what women find attractive will be the main issue. No one is the same.

I recommend brushing up on your reproductive and circulatory anatomy as well, and study the muscle groups within your body that are in and around your points of concern.

If you've been brainwashed into thinking less than 6 feet is unattractive, do yoga. If you've been brainwashed into thinking average length is unattractive, do different styles of squats, deadlifts, and other mid/lower body exercises regularly.

Hydration is terribly important - excess sugar and salt, and 'bad' fats and cholesterol will stunt blood flow. To both brains. If you are willing; exchange the sensation of foods like soda, fatty meats, chips, excess cheese, and fried foods - for a healthier, more performative body and a less depreciative self-perspective - then you will see an improvement on all fronts. But that's contingent on remaining brainwashed to thinking your proportions matter. Consider your anonymous responder the other end of the brainwashed spectrum - and you're lucky to see it. Concerning this matter - some fools can never be satisfied - it's well beyond proportion for them, and for you - it starts with how you see yourself. So don't let these false, compassionless prophets delude you into thinking you can't be attractive.
