Hello Greg,
Having a look at what you've put I'm assuming your aiming for around 3% abv? Without doing the math you will want your Gravity to Bitterness balance to come in somewhere between the .4 and .6 margin.
Your grist is actually fine for the style as a lot of the older Milds of the day often had just pale malt or pale and crystal, with the remainder being made up with sugar and/or roasted malts/adjuncts.
As you will hear many times Mild only means 'unaged' beer, it is entirely possible to have a pale Mild as the majority would have been darkened using Brewers Caramel, take that a way and you get a pale beer.
15% made be a tad high on the crystal, I tend to hover around 10% at most on a simple grist, only going higher on more complex ones. Others will say the Sarah Hughes Ruby Mild is great and that has 20%? Of crystal but for me it is too much.
With the hopping rates I would really cut back on the aroma hop as going by guidelines for your sake, the malt is supposed to be the dominant aroma, for either my dry hop or aroma hop additions on a Mild it is generally between 0.5g/l and 1g/l. Something I have been experimenting with recently is using oak chips either as a dry hop or in the aroma stages of the boil, both have seen positive reviews.
As for the Admiral it is a flavour intensive hop but has virtually nothing in the way of aroma, with such a low grist I would suggest adding then at 60 minutes for less of the strong bitterness and get a little more of the subtle flavours going in.
Next up is the mash temperature, again in previous years Milds and Bitters would have been produced as running beers for breweries and as such would have been mashed low to gain a full attenuation from the yeast, sometimes a full 90 minute mash at 60°, making it watery hence the stigma, more modern versions are mashed anywhere between 65° and 70° to retain some degree of body, for yours I would be mashing in at least 68° but use a good highly attenuative English yeast strain.
Invest in a vial of White Labs, Wyeast or Brewlabs and learn to crop, you won't regret it. The range of attenuation you will be wanting is at least 75% to leave some residual sweetness but to dry it out so it doesn't make it cloyingly sweet (something I didn't know before).
My two best examples that have been reviewed have been a Ridleys Mild clone using 95% Pale Malt, 5% Chocolate Malt and 11% Sugar by weight and a Tolly Cobbold Mild clone of 85% Pale Malt, 10% Crystal Malt and 5% Chocolate Malt, both with 20 - 30g of oak chips for a dry hop and weighing in at 3.5% abv and 3.2% respectively.
There is also some information on my blog about making traditional and modern Milds, always there if your interested.
Any other questions just ask
