This bug report has five parts. Some of these problems are not very problematic but I think it is better to err on the side of lots of suggestions.
Part 1
U+0F04 TIBETAN MARK INITIAL YIG MGO MDUN MA and U+0F05 TIBETAN MARK CLOSING YIG MGO SGAB MA are meant to connect to each other like ⟨༄༅༅⟩. The same goes for U+0FD3 TIBETAN MARK INITIAL BRDA RNYING YIG MGO MDUN MA and U+0FD4 TIBETAN MARK CLOSING BRDA RNYING YIG MGO SGAB MA. U+0F06 and U+0F07 are not wrong, but I have suggested new glyphs for them to match the suggested glyphs for the others.
U+0F19 TIBETAN ASTROLOGICAL SIGN SDONG TSHUGS should be a bit lower to avoid bumping into digits.
The astrological symbols U+0F1B through U+0F1F are squished compared to the other astrological symbols U+0F1A, U+0FCE, and U+0FCF.
U+0F3E TIBETAN SIGN YAR TSHES should be shifted right to avoid bumping into digits.
The loop of U+0F58 TIBETAN LETTER MA doesn’t look as it ought.
U+0F6A TIBETAN LETTER FIXED-FORM RA should look exactly like U+0F62 TIBETAN LETTER RA.
U+0F6B TIBETAN LETTER KKA and U+0F6C TIBETAN LETTER RRA should look like U+0F40 TIBETAN LETTER KA and U+0F62 TIBETAN LETTER RA reversed.
The long vowels U+0F71, U+0F73, U+0F75, U+0F77, and U+0F79 are inconsistent in how they render the ’a-chung. My suggested glyphs make them look more like U+0F60.
The syllabic liquids U+0F76 through U+0F79 don’t look like the sequences to which they are canonically/compatibly equivalent to.
U+0F7F TIBETAN SIGN RNAM BCAD should be shifted right to avoid bumping into consonants.
U+0F88 TIBETAN SIGN LCE TSA CAN, U+0F89 TIBETAN SIGN MCHU CAN, and U+0F8C TIBETAN SIGN INVERTED MCHU CAN should be lower to avoid bumping into diacritics above.
U+0F89 TIBETAN SIGN MCHU CAN, U+0F8C TIBETAN SIGN INVERTED MCHU CAN, U+0F8E TIBETAN SUBJOINED SIGN MCHU CAN, and U+0F8F TIBETAN SUBJOINED SIGN INVERTED MCHU CAN needn’t be so small.
U+0FCF TIBETAN SIGN RDEL NAG GSUM is asymmetrical.
U+0FD2 TIBETAN MARK NYIS TSHEG should look like two stacked U+0F0B TIBETAN MARK INTERSYLLABIC TSHEGs.

Part 2
The subjoined consonants are at inconsistent heights and many of them bump into vowels below.

Part 3
Some of the base consonants overlap subjoined consonants, and some of those can be shortened without completely messing up the glyph.

Part 4
One of those shortened base consonant suggestions differs from the current glyph sufficiently that its subjoined form should change to match it.
0F94:000000000000000000000000000000001E00200040007C000200000000000000
Part 5
All the Tibetan glyphs (all but two with my suggestions) are two cells wide. This is unnecessary and makes Tibetan text look like it has wide letter-spacing: most of the glyphs’ ink is completely within the left half or the right half. All the letters and digits and many symbols can have their blank right halves removed. U+0F3E and U+0F7F can have their blank halves removed and be made into spacing glyphs.
